You cannot both "GLOB" and "TO_CMAKE_PATH" which are distinct
(and exclusive) command options from  the FILE command.
for more detail see cmake --help-command FILE

You usually

1) Transform whatever [eventually escaped] path to CMAKE representation
   SET(A_PATH "S:\\software\\data\\profiles.xml" )
   FILE(TO_CMAKE_PATH ${A_PATH} A_PATH_CMAKE)

   This is useful when you obtain the path from env var too:

   FILE(TO_CMAKE_PATH "$ENV{MYENVAR}" MYENVAR_CMAKE)
   
2) Then use the xxxxx_CMAKE var for other cmake command

   For example finding a program in the path obtained from env var:
   
   FIND_PROGRAM(MY_PROG
                NAMES myprog 
                PATHS ${MYENVAR_CMAKE})

Use FILE first to transform any PATH into cmake representation
then use whatever CMake  command you need with it 
(including ADD_SUBDIRECTORY)
